'Drlginal application med July 2, 1910, Serial No. 670,138. Divided and this application tiled Actohcr 4, A 1910. Serial No. 585,281.

To au whom it may concern: Be it known that I, ToNJEs AUoUs'r C-Aiin Born, a citizen of the United States, and u resident of New York, in the county of New Yrk an State of New York, have invented certain new and useful Improvements in Mechanical Movements, of which the following is a. specification, taken in connecti'on with the accompanying drawing, which forms a part of the same.

This invention relates to mechanical movements adapted for universel application, and is a division of my co-pending application Serial No. 570,138. I have shown my mechanical movement located in an electric light socket and adapted to make and break the current therein, though it is to be distinctly understood that my invention. is not to be limited to this or any other particular use.

My invention further relates to an electric light key socket in which my improved niechanical movement is used, all of which will be hereinafter described in the specification '25 and pointed out in the claims.

In the accompanying drawing showing illustrative embodiments of my invention.

and in which the same reference numerals refer to similar parts in the several figures,

Figure 1 is avertical section through my double pole electric light socket; Fig. 2 is a vertical section substantially on the line 2-2 of Fig. 1; Fig. 3 is a horizontal section on the line 3-3 of Fig. 1; Fig. 4 is a detail perspective view of,pne form of conducting or bridge plate; Fig. 5 is a detail rspective view of one form of driven ineinbr; Fig. 6 is a diagrammatic view showing the passage of the current in my double pole socket; and Fig. 7 is a detail vertical section on a reduced scale.

In the illustrative embodiments of the invention shown in the drawing, 1 is an electric light. socket having the usual or any approved outer shell 2, a cap 3 and with any form of insulation 4 between the shell and the screw shell contact 5, Fig. l. The insulation which is usuall used to line the rap 3 may bc employed, if desired, but preferably is omitted. The shell, cap and insulation forni no part. of nl v invention and therefore will bc disregarded in the further description of thc invention.

'lo house and thoroughly protect my mechanical movement, when it is used as the -the screw shell contact 5.

operating switch mechanism in an electric light socket, I mount it in the interior 6 of a hollow insulating receptacle 7 usually formed of porcelain or some other suitable material. This receptacle 7 is closed on all sides except 60 the bottom which is closed by the head 8 of This screw shell contact is held to the closed insulating receptacle 7 in any suitable manner such as by means of the screws 10, 10, Figs. 3 and 7, 85 coperating with nuts 11, 11, Fig. 7. The upper portion of the screw shell is cut away at 12 for the reception of the center contact 1a, Fig. 1.

The screw shell contact 5 is provided with 70 an upwardly extending screw shell contact 14 arranged opposite and separate from a spring contact 15 connected to the binding post contact 16. Within the interior 6 of the closed insulating receptacle 7 I also pro- 75 vide a spi-ing contact 17 connected with the center contact 13 and arrange it opposite to, and separated from, another spring contact 18 which is connected te the binding post 19. The center contact 13 is insulated from the head 8 of the screw shell contact 5 in any suit-able manner such as by a piece of mica 36.

0u the driving member-20 I spline a porcelain or other insulating driven member 21 85 having at one end u rim 22 and at the other a rim 23, und upon cach rim I mount a con ducting or bridge plate 24, 24, such for exaiuple as shown in Figs. 4 and These plates 24 may be secured to the porcelain or 90 other insulating driven member 2l in any suitable manner. Preferably,l secure them by providing them with ears 25. 25. which can be beni around the rims 22 and 23. The driven member 2l between the conducting or 95 bridge plates 24, 24. is provided with oppositely inclined surfaces and 29 forming opposed hills 30 and valleys 31. Upon these hills and valleys any suitable resilient inmuhoi' is adapted to operate. such as the spring 10 32 shown in Fig. 2. This driven member 2l is also preferably provided with locking moans to hold both ends 34, 34 of thc spring 32 until such time as the maximum energy has been stored up in the spring by partly 105 rotating thel driven member with its hills between the ends 34. 34 of the spring. A cheap and economical means to hold both ends of the spring is to provide each hill with a pair of locking notches 35, 35 which 11 will coperate with the ends 34. 3l of the spring 232 and hold them from sliding down the incline surfaces of the driven member until the driven member has fully conipleted its partial rotation. The spring will then act with its maximum et'feet and insure a q'iek aml positive snap of the driven member to and froin'the tixed contacts. lt will therefore be seen that in this forni of in v invention tlie electric light. socket is a double pole one. there being four eontaets. two for eaeh wire. TWhen the driven meinber 21 is in the position shown in Fig. il wherein the forward eonduetiiig or bridgtl plate 24 is brought into contact with its respective ,spi-imglr contacts l l. i5, and the rear conducting;r or bridge plate it ist brought into contact with its spring eontacts 17. 1S. the current will pass as shown diagranunati falli' in Fig'. t coming in at the binding post l!) passing;r through its springr contact 1S, rear bridge plate 24 on the driven member Q1. spring' Contact 17, thence through the eenter Contact 13, through the lamp or othei' 25 consuming device {if} ack to the shell contact 5, spring Contact. 14. forward.bridge plate Q4, springtr Contact l5 out through the bindingr post tti;

A partial rotation of the driving' member Q() in either direction sutlieient to cause the spring 3'2 to cooperate with the opposed hills and valleys, as previously described. will cause the porcelain or insulated driven meinber :'21 to snap back and quickly break all four contacts. further partial rotation ot' the driving member 20 andthe driven meniber 21 will cause the latter to reverse its movementand quickly snap the respective conducting` or bridge plates 2i. Il between 40 their respective spring contacts and therebv luiekl" make theeleetrieal eonneetion. This double pole socket permits currents of high voltage to be safely used. B v using niv nieehanieal movement. as a switch mechanism for such a double pole socket. all four eoutants are not only quiekly broken. but are also quickly made; both the making and breaking being almost instantaneous and therebv eliminating :ill art-ing on the making as well as the breaking of the current.

lt. will be timed that in v invention is pai'- tieularly adapted for a double pole key soeket which can be turned otll or on in; either direi-tion of rotation of the driving member, or key, insuring both a quiek make and :i quick break regardless of the dii-ee tion of rotation ot' the key.

'llie driving member is provided with :in v

suitable loekiiig means to hold it within the closed insulating reeeptaele i. li'et'erablv l provide it near one end with a eireumfereutial groove Ilt to cooperate with a loekin.;r plate 3T whieh is mounted in au opening: g 3S in the closed insulating reeeplaele T. A\fter the locking plate 2li is mounted to eooperate with the groove 9.8 it might. be held in this groove by an)v suitable m aus such as b v the insulation 3f).
